Background: Non-variceal upper GI bleeding (NVUGIB) is a common medical problem that has signifi cant association with morbidity and mortality. Angiographic detection and subsequent transarterial embolization (TAE) is a primary treatment option when medical and endoscopic treatments fail. We investigated clinical factors that could affect the success of the angiographic detection and prognosis after TAE in patients with NVUGIB refractory to endoscopic therapy. Methods: A retrospective analysis of the clinical data was done in patients with failed endoscopic treatment who underwent angiography for the treatment of acute NVUGIB between May 2002 and May 2013. Patients were divided into detection or non-detection groups according to the presence of bleeding stigmata in angiographic fi nding. Rebleeding defi ned as subsequent bleeding event within 7 days and mortality within 30days were analyzed as outcome parameters after TAE following detection in angiography. Results: A total 45 patients 37 (male, mean age, 65.9±14.9 years) were analyzed and classifi ed as a detection group (n=25, 55.5%) and non-detection group (n=20, 44.6%). Peptic ulcers were the most common cause of refractory NVUGIB. Larger transfusion amount (5.7±3.9 unit vs. 3.5±2.8 unit; P=0.03), prolonged aPTT level (34.2±17.3 sec vs. 21.8±13.8 sec; P=0.01) and short time interval between last endoscopy and angiography (17.5±25.9 hours vs. 34.3±59.5 hours; P=0.04) were found to be signifi cant factors for predicting angiographic detection. TAE was performed in all patients detected in angiography. Rebleeding (44%) was significantly associated with higher Rockall score (8.3±1.5 vs. 6.6±2.4; P=0.046) and mortality (12%) was signifi cantly associated with higher Rockall score (9.3±0.6 vs. 7.1±2.2; P=0.002) and higher level of BUN (55.3±47.4 vs. 27.6±17.4; P=0.01). Conclusions: Clinical characteristics associated with angiographic detection in patients with NVUGIB refractory to endoscopic therapy were severe bleeding, bleeding tendency and early angiographic intervention. The Rockall score is useful parameter for predicting rebleeding and mortality after TAE.

Switched Reluctance Motor의 진동, 소음 특성해석에 관한 연구

정태욱,최태완,이태환 진주산업대학교 2000 산업과학기술연구소보 Vol.- No.7

Switched reluctance motor(SRM) drive system is to be compatible for wide range adjustable speed motoring system because it has the same driving characteristics of DC series motor, easy control principle and high efficiency characteristics. By this reason, SRM drive system will be applied to many commercial adjustable speed application that requires economic advantages and high performance abilities. But, SRM drives generate large vibration and acoustic noise because it is rotated by step pulse mmf and switching commutation mechanism. This disadvantage has been obstacles to applicate SRM drives as generalized motor drive system. The main origin of vibration and noise is caused by commutation method which applies step pulse waveform mmf to stator pole and removes the mmf suddenly. This sudden variation of stator flux vibrates stator frame by radial direction and excites natural vibration mode of stator. This paper analyzes the characteristics of vibration and acoustics noise of SRM from the viewpoint of natural mode and driving coidition, and consider the reduction strategy of that.

This study has been made investigation for the difference of fatigue strength under variable cyclic-rate, compared with three types cyclic-rate 2700cpm, 750cpm and 100cpm using smooth specimens(Kt=1.025) and center holed specimens(Kt=2.02) of SCM 440 steel were obtained through fatigue tests in the rotating. The following conclusions were obtained 1. The specimen(SCM 440) is continuously softened in the field of low cyclic rate. 2. The fatigue strength become high in case of big stress intensity factor. 3. The crack growth life become fast in high stress level. 4. The time of failure can be predicted in the same conditions.

安泰煥,金仁湖 慶尙大學校 1989 論文集 Vol.28 No.2

우리나라의 慶尙南道 晋州地方에 位置하고 있는 晋州測候所(35°12'N, 128°06'E, 標高 25.1m)에 의하여 1983年 1月부터 1988年 12月 까지 觀測된 主要氣象要素의 觀測値를 基礎資料로 하여 G. Taylor의 climographic 提衣에 의한 晋州地方의 年別 및 平均別綜觀 climograph를 作成하고 이들을 比較한 考察한 바, 이 地方의 氣候特性은 대체로 高溫多濕한 서를 나타내고 있으며 또한 우리나라의 ??에 속하는 氣候形이 현저하게 나타남을 알 수 있었다. 또한 本調査硏究 其間의 最近 數年동안은 平均에 비하여 약간 低溫多濕한 氣候變化의 樣相을 보이고 있음을 알 수 있으나 이에 관해서는 보다 長期的인 觀測資料에 의한 分析的이고 綜合的이며 持續的인 硏究가 있어야 할 것으로 思料된다. 끝으로 本硏究의 遂行을 위하여 各種資料收集에 도움을 주신 中央氣象台 釜山支台 晋州測候所의 南大佑先生님을 비롯한 여러분과 電算處理에 수고해준 慶尙大學校 師大 物理敎育科 電算室 여러분께 깊은 感謝를 드립니다. The climograph which is used for the comparative study on the climatic characteristics between one region and another is considered as one of the representative methods. The climographs based on the observed meteorological materials for six years(Jan, 1983~Dec. 1988) in the Jinju district were shown in Fig. (1) ~ (7). From the analytic results the tendency of climatic changes with slightly low air-temperature and much moisture in several years(1984,'86,'88) was comparatively different from the normal climatic changes. By the G.Taylor's climographic analysis, the climatic characteristics of this district were remarkablely presented one of southern coastal type(SC or CS).

外國의 老人居住形態와 統合計劃의 類型에 관한 硏究

One of the first considerations that invariably arise in planning housing accommodations for the elderly is whether new accommodations would be "segregated" or "integrated". Behind the decisions to build any of the particular types of projects described above have been two types of factors, which may be boardly classified as social and economic. Usually where the larger groups or clusters of apartments for the aging have been built together, the economic factors predominated. It has been considered more economical to build and provide services for elderly individuals and families if they were concentrated in centralized locations. On the other hand, where there has been a mixing of apartments for older and younger families, the social factor predominated. It has generally been considered desirable not to isolate the elderly from younger persons but rather to encourage as much socialization as possible between the two groups. Sometimes these concepts have acquired "segregation" and "integration" levels. A degree of segregation seems to be preferable to the extent that small clusters of old people can live together, and a degree of integration seems preferable to the extent that old people are not completely isolated and have the opportunity to mix with the general population when they desire.

This fundamental study put the aim on the establishment of Gwangju Metropolitan Open Space System where the region was assigned to Metropolitan Plan Area of The 4th Comprehensive National Territorial Plan in Korea. This studied region is composed of Gwangju and Naju city and Damyang. Hwasoon country and a part of Hampyoung country where the area is 2994.91㎢. Now the GIS is well known system for characterizing spatial relationship, especially the tool for seeking proper site for decision making. But the boolean method which is usually used with map overlay technique in GIS has couple of problems in the field of spatial database management and interpretation. The failure of constructing continuous value is one of the typical problem which based on the simple set-True or False-system, while the spatial relationship has variety and complexity. So the study focused on the application of Fuzzy method with AHP technique which are relatively new to in using GIS. The merit of Fuzzy method is to keep values which existed between the two critical values and these values are useful for giving flexibility to decision making. AHP with Pairwise Comparison method can minimize the problem which occurs from adding extra value by subjectivity that is one of the important pitfalls of using GIS. The results of application of Fuzzy method with AHP showed much differences in the area of suitability of open space when compared that of boolean and achieved flexibility through the levels of suitable site for the open space area. This study was carried out with several basic factors only. The more factors should be dealt and the way of detailed interpretation of continuous data existed as luminosity in modeling should be studied. Also the distribution and giving functional value to open space system are the theme which should be deveolped for further study.
